Description
Located on the Fall Line that marks the transition from Coastal Plain to the rolling hills of the Piedmont, Prince William Forest Park is metropolitan Washington D.C.’s largest park. Over 17,000 acres of mature hardwood forest, interspersed with springs, fens, creeks, and ponds, provide habitat for woodland birds and other wildlife. White-tailed deer, wild turkey, and beaver can be found along the park’s 37 miles of trails. In winter, migratory waterfowl fill the ponds. In summer, the wood thrush and other breeding songbirds occur here in large concentrations. Neotropical migrants, particularly woodland warblers, abound during the spring and fall. A bird list, map, and other information are available at the visitor center.
